An integrated eddy correlation system is described. This system comprises a multi-headed sensor, a real-time processing unit and software for analysing and storing the data on a microcomputer. The instrument, known as the Hydra, was first used for research in 1981. Since then, experience gained in using the instrument on four separate research projects has been applied to the redesign and production of an improved instrument designated the Mark 2. This instrument is described together with two applications, the first over a millet crop in the Sahel region of West Africa and the second over a pine forest in south-west France during the HAPEX experiment.
